Throttle/Pedal Position Sensor/Switch B Circuit Low Input

The backup throttle position sensor is sending a signal that is lower than what the engine computer expects, indicating a weak or faulty sensor signal. This may cause the engine to run lean, hesitate, or stall, especially during acceleration. The sensor or its wiring should be inspected and repaired or replaced.
